HEATING DEVICE.

Appiication filed April 9,

To all whom it may concern:

Be it known that I, HERMAN E. Hours, a :itizen of the United States, and a resident 9f New York, in the county of New York and State of New York, have invented an improvement in Heating Devices, of which he following is a specification.

My invention relates to electric heaters and the object thereof is to provide a heater if improved design and construction. In he drawings accompanying this application have shown, for purposes of illustration, me embodiment which my invention may :ssume. In these drawings,

Figure 1 represents a front view of my ieater with certain parts broken away,

Figure 2 represents'a horizontal cross sec- ;ion of my heater showing the fan in eleva- 31011,

Figure 3 is a detail of the bridge to which he heater wires are secured,

Figures 4 and 5 are details showing the mounting of the heating elements,

Figure 6 is a detail showing the socket which I employ, and

Figure 7 is a detail of the clip by which the heater may be secured to the fan guard.

The heater herein disclosed is provided with a suitable frame 11 adapted to be secured to any desired part of the fan such as the fan guard 12 and provided with a front portion 13, preferably of the contour generated by rotation of a. parabola about a line parallel to the transverse axis, adapted to deflect the air to cause it to flow in all directions radially of the axis of the fan. Means are a so provided to heat 'the air current and this heating means is herein shown as an annular heating unit arranged between the rim of the deflector and fan guard and comprising a plurality of heating elements 14 each supported between lugs 15 and 16 struck up from the cylindrical portion of the frame 11 to coincidently support the elements and provide openings through which the heated air may be driven.

The frame 11 may be secured to the fan uard in any suitable manner such as that Eerein illustrated in which I employ a plurality of clips 17 each arranged to extend about a radial member 118 of the fan guard and through apertures 19 in the frame 11. A clip is positioned by inserting: the end 1920. Serial No. 872,414.

20 through one of the apertures 19 up to the intermediate locking position 21, then rotating the clip about the point 21 as a center to move the end 22 through a second aperture 19 up to the intermediate position 23, and after this moving the clip bodily to cause the end 20 to engage the frame at the final lockin engage at the final locking point 25. The clip is resilient and is held in its final locked position by this resiliency and also by the angular relation between the frame and the surfaces of the clip in engagement therewith, the portions of the ends 20 and 22 between the intermediate and final locking positions being disposed, when in final locking position, at such an angle to the frame that tension on the base of the clip will cause the clip to seat tighter rather than to pull out.

The wires supplying power to the heater may be secured to the heater frame in any suitable manner but I prefer to use the construction herein shown in which a bridge 25' is secured ,to the frame of the heater and supports an oppositely arched bridge 26 to which the wires are attached.

In using my heater I find it convenient to insert the heater plug into the receptacle formerly occupied by the fan plug and to provide on the heater a receptacle for the fan plug suitably connected to the heating circuit. For this purpose, I may use one of the receptacles now in use or I may use that receptacle shown in detail in Figure 6. The receptacle of Figure 6 consists of a porcelain body 27 apertured at 28 for the reception of the lead-in wires, a metallic member 29 screw threaded as at 30 to cooperate with the usual plug and provided with the usual center contact 31, the member 29 and contact 31 being suitably connectedto the lead-in wires in any desired manner, and surrounding this entire structure and holding it in position, a. shell 32 arranged at both top and bottom to be turned over the enclosed structure and thereby locked in securing position. This socket may be supported on the frame 11 by providing the shell 32 with a plurality of struck up lugs 33 arranged to be bolted or riveted to t e frame. I

It will be understood that the embodiment of mfy'invention herein shown is for point 24 and the end 22 to purposes of illustration and that my invention is not limited thereto.

ll claim 1. In an electric heater, a device for supporting the wires leading from said heater comprising abridge member secured to the frame of said heater and a second bridge member reve-rsely positioned secured to said first bridge member and provided with means to which said wires may be secured.

2. In an electric heater, a device for supporting the wires leading from said heater comprising a bridge member securedto the frame of said heater and a second bridge member reversely positioned secured to said first bridge member, arched oppositely thereto, and provided with means to which said wires may be secured.

3. lln an electric heater arranged for use with an electric fan, means arranged to do? fleet the air radially of the axis of the fan comprising a deflector of such contour that it is positioned near the fan at the center thereof and slopes away from the fan in all directions.

4:. iii an electric heater arranged for use with an electric fan, means arranged to defleet the air radially of the axis of the fan comprising a deflector of such contour that it is positioned near the fan at the center thereof and slopes away from the fan in all directions, and an annular heating unit positioned between the rim of said deflector and said fan. j

5. In an electric heating device for use with an electric fan,.means for deflecting the air radially of the axis of said fan comprising a deflector generated by the revolution of a parabola about a line extending trans- Verse to the principal axis thereof and positioned symmetrically in front of said fan with the central point thereof extending toward said fan.

6. In an electric heating device for use with an electric fan, means for deflecting the air radially of the axis of said fan comprising a deflector generated by the revolution of a parabola about a line parallel to the transverse axis thereof and positioned symmetrically in front of said fan with the central point thereof extending toward said fan, and an annular heating unit arranged Eetween the rim of said deflector and said 7. In an electric heater arranged for use with a fan constructed to set in motion a current of air in an axial direction, a heating element and a deflector arranged to cause said current to spread and flow radially in; substantially all directions in a plane perpendicular to the axis of the fan.

8. In an electric heater arranged for use with a fan constructed to set in motion a current f air in an axial direction, a deflector arranged to be supported in the path of the air current of the fan transverse to the direction thereof and to spread the air current in radial direction and a heating element arranged peripherally of said deflector to heat the deflected air current.

9. In an electric heater arranged for use with a fan constructed to set in motion a current of air in an axial direction, a deflector, a heating element arran ed along the periphery of the deflector, the deflector being arranged, when supported in the path of the air current set in motion by the fan, to spread the air current and deflect it in diverging radial directions and into-contact with the heating element.

10. In an electric heater arranged for use with a fan constructed to set in motion a current of air in an axial direction, a de flector arranged to be supported in a plane transverse to the fan axis and to deflect the air current radially and a heating unit arranged along the periphery of the deflector in thespatl of the deflected air current.

11. An electric heater arranged for use with a fan and adapted to be supported concentrically therewith. comprising an annular heating unit and a deflector concentric therewith arranged to deflect the air current from the fan in divergent radial direction and into engagement with said heating unit.

12. A11 electic heater adapted to be attached to a fan in concentric relation thereto, comprising an annular heating element arranged around the periphery thereof and a deflector concentric with said heating element, arranged to be supported transverse to the axis of the fan and to deflect the air current set in motion by the fan in divergent radial directions to the heating element.

In testimony whereof, I have signed my name to this specification this 7th day of April, 1920.
